A Democratic congressman announced Monday that he would refuse to honor a moment of silence held in memory of the people murdered in the Las Vegas mass shooting the prior night.

Police say that at least 50 people were killed and hundreds more were injured when a man opened fire on the crowd at a country music festival from his hotel room. The shooter, identified as local 64-year-old man Stephen Paddock, is not believed to have any religious or political motivation.

In response, Massachusetts Rep. Seth Moulton (D.) said he would refuse to participate in a House of Representatives moment of silence.

As after #Orlando, I will NOT be joining my colleagues in a moment of silence on the House Floor that just becomes an excuse for inaction.
